You honestly believe the world ’ s improving every year ?   Yes , I do . I think that science is making us wiser . What do you think ?   I don ’ t think you ’ re right there .   I believe industry is making us wealthier .   I don ’ t believe that .   And in my opinion , medicine is making us healthier .   I agree with you in the sense . But we ’ re all more miserable than ever , aren ’ t we ?   I don ’ t agree with you . I maintain that we ’ re healthier , wealthier and wiser than we were a hundred years ago .   That ’ s your opinion not mine .
